High Performance Polarization-Based 3D and 2D Presentation
Each digital cinema 3D delivery system has a characteristic efficiency. The 3D-efficiency gives the relative luminance of 3D presentation compared to 2D presentation. In the absence of careful attention to design, component efficiencies, and maintenance, the result can be a peak luminance well below 4.5 fL, even on average sized screens. In addition, aspects of a 3D system can determine the quality of 2D presentation. Given the large installed base and immediate need for higher brightness images, methods for increasing brightness and image quality are sought which enhance existing projector platforms. This paper evaluates loss mechanisms in 3D projection systems and shows that high-brightness 3D is feasible using lamp-based illumination. These solutions can be implemented using single-projector sequential 3D, for conventional sized screens (averaging 40′), as well as premium large format screens in excess of 60′.
